I have a GE potscrubber

I have a GE potscrubber Dishwasher Model # GSD3630ZZ3WW
it has been leaking from the bottom for about a week. I took the bottom off tonight and ran the dishwasher so that I could see where it is leaking from. It is not a hose but the leak seems to be coming from the back of the motor or pump fan where it goes into that plastic housing that attaches to the bottom of the dishwasher seems to be leaking in the very center of that housing where the motor shaft enters the housing. Water is just spraying out of that housing onto the floor below.
